Hey, I just got back and there is a pair of panties outside of my door (white and rather skimpy) - would you say its an obscure practical joke or some girl who thinks I will guess it was her?
Why would a girl do that? (I'm pretty sure none of my male friends did it as a joke, though it might be a female friend) If you are a girl would you do it? Has it happened to anyone else?
Maybe you lent them to someone and they kept them for ages and you forgot that you had lent them out and now that they have been returned you don't know why they are there
Maybe someone dropped their laundry? Or sat on them and didn't realise and they got caught up in their jacket and fell off when they walked along the corridor. Not that either of those things has happened to me.
